To all whom it may concern:

Be it known that I, LUSTER S'rrLEs, Jr., a citizen of the United States, residing at Evansville, in the county of Vanderburg and State of Indiana, have invented certain new and useful Improvements in Oil-Atomfollowing is a specification.

This invention relates to atomizers for oil used to lubricate the cylinders of steam engines and adapted to be connected to the steam supply pipes to mix with the steam therein; and it consists in the novel construction and combination of the parts here'- inafter fully described and claimed.

In the drawings, Figure 1 is a longitudinal section through an atomizer constructed according to this invention. Fig. 2 is a crosssection through the atomizer, taken on the line 0000 in Fig. 1.

The steam supply pipe 2 is shown arranged vertically, but it may be arranged horizontally or at various angles, and the arrows show the direction of the steam fiowing through it from the boiler to the engine.

The atomizer cylinder 3 is preferably slightly tapered, and it is inserted crosswise of the steam pipe 2, and is connected to the pipe 2 by a screwthreaded portion 4;. The cylinder 3 has a row of steam inlet holes 5 and 6 in the side of it nearest the boiler, and the hole 6 is arranged near its closed end 7 The cylinder has also an outlet hole 8 on the opposite side of it from the inlet holes and at about the middle of its length and near the center of the steam pipe. The combined areas of the holes 5 and 6 are considerably greater than the area of the outlet hole 8. An oil supply pipe 9 is connected to the end portion of the cylinder which projects from the steam pipe by, means of a screwthreaded sleeve 10 or any other suitable connection.

A plug 12 is screwed in the outerend portion of the cylinder 8, and a heating tube 14 for oil is screwed into the said plug, and projects longitudinally in the cylinder 3 between its steam inlet holes andthe outlet hole 8. The open end of the tube 14: is arranged substantially in line and crosswise of the center of the steam inlet hole 6.

The oil or similar lubricant is fed into the heating tube by. any suitable supply device, and it is heated in the said tube by the steam which impinges against its outside surface, so that the lubricant becomes very fluid.

pipe, of an atomizing cylinder The oil is atomized as it passes out of the open end of the tube 14f by the steam which passes in a jet through the hole .6. The oil spray mixes with the steam, and is projected with the steam through the outlet hole 8, and is more completely atomized as it passes through the hole 8.

When the oil is mixed with the steam in a fine state of subdivision, it is found that it ".an lubricate the steam cylinder of the engine to better advantage, and a material saving in the quantity of oil required for lubricating the cylinder is effected. The cylinder 3 may be truly cylindrical instead of being tapered, if desired, and several holes 5 may be formed init so that the steam may impinge against the heating tube 14 at various points and heat the oil effectively, and so that the pressure inside the cylinder around the heating tube may be fully that of the steam pipe. The device may be installed in a separate steam chamber or branch steam pipe, if desired, and connected to the main steam pipe in any approved way. This arrangement is desirable when the main steam pipe is too small in diameter to receive the atomizer.

WVhat I claim is:

1. The combination, with a. steam supply pipe, of an atomizing cylinder secured to the steam pipe and projecting crosswise inside it and provided with a closed end and having lateral holes for the inlet of steam and the outlet of steam and atomized lubricant, and an imperforate tube for supplying and heating lubricant arranged longitudinally inside the said cylinder with its outlet end adjacent to the closed end of the cylinder.

2. The combination, with a steam supply secured to the pipe and extendingcrosswlse of it, said cylinder having a closed end, steam inlet holes on one side one of which is arranged near its closed end, said cylinder having also an outlet hole in the middle part of its other side, an imperforate heating tube for lubricant secured within the said cylinder and extending longitudinally of it and having its open end arranged crosswise of the steam inlet hole near the closed end of the said cyl- LUSTER STILES, JR.
